摘要:

我们采用进化博弈的方式研究了无标度网络中的累积财富分布。该系统自组织到一个临界帕累托分布(1897)的财富$P(m)\sim m^{-(v+1)}$与$1.6 < v <2.0$(这是在协议与美国或日本)。特别是,代理人的个人财富与其联系人数量成正比这种现象与社会、经济、科学等领域中存在的马太效应相吻合。虽然我们的模型比较简单,但它很好地代表了经济中的合作和利润积累行为,它将网络理论与经济物理学相结合。

英文摘要:

We investigate the accumulated wealth distribution by adopting evolutionary games taking place on scale-free networks. The system self-organizes to a critical Pareto distribution (1897) of wealth $P(m)\sim m^{-(v+1)}$ with $1.6 < v <2.0$ (which is in agreement with that of U.S. or Japan). Particularly, the agent's personal wealth is proportional to its number of contacts (connectivity), and this leads to the phenomenon that the rich gets richer and the poor gets relatively poorer, which is consistent with the Matthew Effect present in society, economy, science and so on. Though our model is simple, it provides a good representation of cooperation and profit accumulation behavior in economy, and it combines the network theory with econophysics.
